How Does a Car Alarm Protect Your Vehicle from Theft?

Ten years after the automobile was first invented, people were shocked to find out that car theft could be a thing. Since then, car theft cases have just kept growing until new forms of security were introduced in the market to protect your car from being stolen. Today, every car owner makes sure that their vehicle is equipped with a car alarm system in the hopes of scaring away any potential thieves. But how exactly do car alarms work, and why is it considered the go-to security measure for vehicles?

The Basics

Car alarms, at their very essence, aren’t that complicated. It’s basically just a siren that has sensors connected to it. The simplest alarms are made by just putting a switch on the driver’s side of the car. The door would then be wired to activate the siren if someone opened the door. When the sensors don’t record any unusual activity or movement, the alarm remains active but silent and unnoticeable.

Older versions of car alarms usually only include one or two sensors; one for the door and the other works as a tilt/shock sensor. Nowadays, alarm systems work a little differently and are much more sophisticated.

Modern Car Alarm Systems

Modern car alarms are designed to respond to a variety of different security threats that can lead to car theft or other crimes. There’s also break-ins and vandalisms that could still be costly to the car owner. With an alarm system, a simple, loud noise could be enough to deter anyone who will attempt to do something terrible to your vehicle.

Most modern alarm systems also have multiple sensors connected to the alarm’s computer. If one of those sensors detects something unusual or is suddenly activated by a car thief, it will immediately send a signal to the computer and activate the alarm. A typical alarm nowadays consists of:

  • Sensors – These sensors are typically equipped with switches, pressure sensors, or motion detectors.
  • Siren – A siren is a device that creates various sounds to alarm you and other people. Newer alarm systems give you the option to pick a distinct sound for your car.
  • Radio Receiver – Alarms can be controlled remotely using a small remote attached to your key fob. That remote is connected to a radio receiver to allow wireless activation and deactivation of the alarm.
  • Auxiliary Battery – Every car with an alarm system depends on your car’s battery to function. However, the alarm system is also equipped with an auxiliary battery in case the main battery gets drained or disconnected. If a car thief attempts to tamper with or disconnect the battery, the auxiliary automatically kicks in and
  • Computer Control Unit – This monitors all of your car’s functions, including the alarm system and is in charge of sounding the alarm. Essentially, it’s the “brain” of a vehicle.

Some advanced alarm systems even have proximity sensors equipped with perimeter scanners that monitor any activity around the vehicle. There are also microphone sensors that detect sudden loud noises, such as a window breaking.

Conclusion

Car alarms are perhaps one of the most important discoveries in the automotive industry. If paired with other robust security systems, an alarm can give you the peace of mind you’ve always wanted when owning a vehicle.
